Carnation plant named ‘Cristal’

ABSTRACT

A new and distinct cultivar of Carnation plant named ‘Cristal’, characterized by its compact, upright and rounded plant habit; freely basal branching habit; freely flowering habit; and white-colored flowers.

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘Cristal’.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related application (U.S. Plant patent application Ser. No. 11/073,465): Carnation Plant Named ‘Classica’; Johan Edwin Heil, applicant.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of potted Carnation plant, botanically known as Dianthus caryophyllus and hereinafter referred to by the cultivar name Cristal.

The new Carnation is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to develop new compact Carnation cultivars suitable for container production with attractive flower coloration.

The new Carnation originated from a cross-pollination made by the Inventor of the Dianthus caryophyllus cultivar Sunflor Campari, disclosed in U.S. Plant Pat. No. 12,740, as the female, or seed, parent with the Dianthus caryophyllus cultivar Rubato, not patented, as the male, or pollen, parent. The cultivar Cristal was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands, in 2000.

Asexual reproduction of the new cultivar by terminal cuttings at Aalsmeer, The Netherlands, has shown that the unique features of this new Carnation are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The cultivar Cristal has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cristal’. These characteristics in combination distinguish ‘Cristal’ as a new and distinct cultivar:

-   -   1. Compact, upright and rounded plant habit.     -   2. Freely basal branching habit.     -   3. Freely flowering habit.     -   4. White-colored flowers.

Compared to plants of the female parent, the cultivar Sunflor Campari, plants of the new Carnation are more compact, have larger flowers and differ in flower coloration. Compared to plants of the male parent, the cultivar Rubato, plants of the new Carnation differ in flower color as plants of the cultivar Rubato have pink-colored flowers.

Plants of the new Carnation can be compared to plants of the cultivar White Surprise, not patented. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Carnation and the cultivar White Surprise differed in the following characteristics:

-   -   1. Plants of the new Carnation had larger flowers with more         petals per flower than plants of the cultivar White Surprise.     -   2. Plants of the new Carnation were more fragrant than plants of         the cultivar White Surprise.

Plants of the new Carnation can also be compared to plants of the cultivar Classica, disclosed in U.S. Plant patent application Ser. No. 11/073,465. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Carnation and the cultivar Classica differed in the following characteristics:

-   -   1. Plants of the new Carnation had narrower leaves than plants         of the cultivar Classica.     -   2. Plants of the new Carnation were not as freely flowering as         plants of the cultivar Classica.     -   3. Flowers of plants of the new Carnation were more fragrant         than flowers of plants of the cultivar Classica.     -   4. Plants of the new Carnation and the cultivar Classica         differed in flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Carnation, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation. The photograph comprises a top perspective view of a typical flowering plant of ‘Cristal’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in Aalsmeer, The Netherlands in a glass-covered greenhouse. During the production of the plants, day temperatures were about 15° C. and night temperatures were about 8° C. Rooted young plants were planted in 10-cm containers and pinched once. The photographs and the description were taken about five months after planting.
